With all due respect to Jennifer, your post needs to be answered.
First, Jennifer is correct. Your question should not be in the Small Claims area... it is potentially a criminal matter.
I also feel that the Small Claim court would probably NOT be the correct forum for your claim. The SC courts are generally limited in the types of cases that they can hear. As such, if you are serious about considering slander or liable case, you should certainly consult an attorney. You need to be aware that your claims (liable and slander) are VERY hard to prove, and even harder to prove that you have been damaged.
The first amendment gives each of us the right to voice our opinions, even about someone else and even if we are later proven to be wrong. You will be forced to not just prove that the statements were made, but that the person making them KNEW that they were wrong at the time of the utterance and that they did so in order to damage you. And if you are able to prove that, you will need to try to prove how you were damaged. Did you lose income?? Did this loss of income cause you to lose your home or car, etc.? You can't just say, "He/She said something that was incorrect and it hurt my feelings." With the exception of emotional distress, 'hurt feelings' are not compensable.
I agree with Jennifer's summary... assuming that you are truly innocent, your friends and fellow club members will realize that. If you are guilty as charged, they will also realize that.
